ugh. . . hurry up and get one lol.
The DS is a great system with a very impressive library, just make sure you get the right games.
The games on the DS are quite different than the games on the Wii, portable games are always different than console games. (in both good and bad ways)
I really think the DS is a great system, the touch screnn is even more innovative tan the Wiimote imo. Bringing the touch screen into portable gaming was really ingenious on Nintendo's part.
